When the minimumWidth/Height of the attached Layout of the mainItem
would change. The following events would happen -
- updateMinimumWidth is called
--> results in resizeEvent being called
--> results in syncMainItemToSize
--> results in slots connected to mainItem widthChanged
---> syncMainItemToSize + syncToMainItemSize being called a few more
times. It's not entirely apparent why at thist point.
This kind of logic is quite hard to follow and more importantly because
of the timers in the middle, an extra paint event is called. This means
the user can first see the window resize and then the item getting
resized.
This patch introduces a little bit of code duplication (can be fixed in
future commits) to clearly establish what updateMinimumWidth should be
doing -
* disconnect signals to make sure mainItem's widthChange is not triggered
* update window size + item size + borders
* reposition if required
The repositioning is useful as currently if a dialog becomes wider if
will not reposition itself and will overflow. With this patch we always
make sure the entire dialog is shown.
Minor Point: On testing without the patch the dialog does reposition
itself if it is not already overflowing. I suspect this is kwin moving
the window.
A test called dialog_minWidthHeighRepositioning.qml can be used to see
how the change occurs before and after.
QQuickLoader is a focus scope so that it can automatically forward the
focus to it's item. Conditional loader should do the same and forward
the focus to its internal loader.
Setting the focus is a good thing, the problem with forceActiveFocus is
that it will not allow any child to receive the actual focus, instead
the focus is forced on to the root element of the applet which may not
be desired.
When for example trying to improve keyboard focus behavior of KickOff
without this patch I cannot get the initial focus on the list of
favorites since it gets reset after the applet is created.

we were creating new packagestructures on each package creation
and never deleting them, causing a pretty big leak.
now keep a single instance of the structures, with prototype packages.
members are static for binary compatibility.
i would go for max one bic change in this library that's when and if
this library will be made pubic.
Patch by Aaron Seigo
consider a loaded package valid even if !isvalid() but does have some file
that indicates it has a valid packagestructure.
for how packages are loaded now, a package is never valid at first if has a required file:
because the path gets set only after the package is loaded
this fixes wallpaper loading
At the moment it's trying to translate the item position and iterating
through all screens, but we can get the screen through the item's window.

Apparently in nvidia we get corruptions when a texture created for a window
is used in another one.
With this patch we tell the texture has changed when we move it from a
window to another, so it's re-created and we keep textures for all windows
separately. This way we ensure they don't mix.

We previously only supported compose-over-border when the centre was not
set to tile.
It's possible to use compose over border with tile.. even if it doesn't
make much sense.
Given that creating an opacityMask loads most of the image anyway, we
can make use of the FrameSVG painter path and avoid any additional code
complexity here.

It was needed, after this we realized that the buttons looked odd,
in some cases, because the center wouldn't be under the 2px wide
sides.
This reverts commit e34d89a1f5.
Breeze theme usually has borders and center that can be tiled, which
ends up in more performant rendering, as we don't need to re-render
anything from the svg every time we resize an element.
Basically what we did was "s/hint-stretch-borders/hint-tile-center/g".
The only exceptions we found for this were: picker, dragger and monitor.

Revert the changes in contentsRect, it was clearly not the best place to
put the code that contains the code that computes the content size.
Instead move the code in FrameSvgItem, duplicates data and code but works.
Use FrameSVG as 9 tiles instead of uploading a big texture of the finished frame each time.
This also saves the cache being populated with full created frames in different sizes; which end up taking up space in the disk and shared memory cache as well as the GPU memory.
A code path falls back to the original uploading the entire texture if obscure settings are used, i.e overlay.
Benchmarks:
apitrace when resizing a frame goes from an average of 7.6ms per frame of CPU time just for the swizzling and uploading to 1.4ms
GPU time also drops from 40us to 10us
Themes will need to remove stretch-borders (when we gain nothing from stretching; i.e Breeze) to get the most out of it.

It's unreasonable to use private API, so make everything public API so that

While debugging a glitch I found out a bug in the painting code that hide
behind QRect documentation. See comment in sectionRect. This never rendered
correctly.
This reverts commit c38e6a204e.
This causes problems on the panel toolbox.
We were already trying to set a parent; however as it's a property of a QQuickItem
it only changes the visual parent; kdeclarative has a code path that if there's
a visual parent to skip the memory management; bug is probably there instead.
This originates from the request of downstreams to hide packages that are still installed.
why should be easier than not installing them i don't know, *but* semantically I think it makes sense act as if the package was not existing when the metadata says it's hidden

Currently the grid itself is composed of 88 rectangles that draw all the
lines in a way that two big rect draws the whole two topmost horizontal
and leftmost vertical border lines and then each day rectangle is
drawing small bottom and right rect.
This patch reduces it to 13 rects only where one rect draws the whole
frame around the grid and then 1px wide/high rects draw the inner lines.
Results in much cleaner & simple code.
Plus there's a small refactor on the id names so it makes more sense.
This does not require any additional changes in the applets.

While profiling plasmashell memory usage with Vishesh we realized that most
of the usage came from loading the Background image repeatedly.
We traced it back to this change, where we were connecting to
wallpaperChanged before initializing it, so it would initialize it again,
loading the wallpaper twice. It's not that we were leaking the object,
AFAIK, but loading an image using QQuickImage already raises the memory
quite a bit.
This change alone reduces by 15% the memory usage of my plasmashell (with 2
screens, that makes it a bit worse, because there's 2 DesktopViews then).
